Blockchain Video Signing for Visual Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital signature technologies are impersonal, error-prone, and lack visual authentication of the signer, as they rely on single-dimensional processes and email-based verification without visual confirmation.
Innovation Solution
Implementing a blockchain-driven system that integrates video conferencing for document signing, allowing visual verification of the signer and recording the signing process, which is then stored with a hash value to ensure immutability and authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional email-based digital signature authentication is used, then the signing process is simple and fast, but visual confirmation of the signer's identity is lost and the process becomes impersonal
Solution Approach 1:
The patent combines video conferencing technology with the digital signature process, merging identity verification and document signing into a single integrated workflow. The video call enables visual confirmation of the signer's identity while the electronic signature pad captures the signing action, creating a unified process that enhances reliability without requiring separate authentication steps.
Solution Approach 2:
The patent adds a temporal and visual dimension to the traditional digital signature process by recording the entire signing event via video. This transforms a static, impersonal electronic signature into a dynamic, verifiable event with visual evidence, allowing later verification of the signer's identity and signing behavior without complicating the initial signing action.
2Reliability
If video recording of the signing process is implemented, then visual confirmation and authenticity are enhanced, but data storage requirements and processing complexity increase
Solution Approach 1:
The patent extracts only the essential elements from the video recording for storage and verification purposes. Rather than storing the entire video file, the system captures key frames, metadata (timestamp, participant information), and hash values that represent the signing event. This extraction approach maintains authenticity verification capability while significantly reducing storage requirements.
Solution Approach 2:
The patent transforms the video data into different parameter representations suitable for blockchain storage. By converting video content into hash values and structured metadata with specific parameters (timestamp, signer identity, document ID), the system maintains the ability to verify authenticity while adapting the data format to efficient storage and verification requirements.
3Stability of the object's composition
If blockchain technology is used to store video and document data, then immutability is achieved, but storage costs and system complexity increase
Solution Approach 1:
The patent creates cryptographic copies (hash values) of the video and document data for blockchain storage rather than storing the original large files. These hash copies serve as immutable verification tokens that prove the existence and integrity of the original documents without requiring substantial blockchain storage capacity, thus achieving immutability with reduced complexity.
Solution Approach 2:
The patent introduces an intermediary layer between the video/document storage and the blockchain. This intermediary computes and stores only the cryptographic hashes and essential metadata on the blockchain, while the actual video and document files are stored off-chain. This mediator approach enables blockchain's immutability benefits while avoiding its storage limitations and reducing overall system complexity.

AI summary
Systems, devices and methods are provided for blockchain driven embedded video and digital signatures on signed documents. The present disclosure includes providing a video conference initiated with the process of signing a document. The video conference and the signing process and the video are recorded. The recorded video captures all conversations, understanding and the final signing by participants. Both the signature and the recorded signing event in video conference are stored with a hash value as a blockchain.
